Last week we reported that Engadget had a rumor that Best Buy would soon offer Barnes & Noble’s e-reader, NOOK, for sale. Best Buy has now confirmed they will offer the NOOK beginning April 18th. As Best Buy put it, the date is “just in time for Mother’s Day, Father’s Day and graduation gift season.”

Previous to this announcement, the NOOK was only available via the Barnes & Noblewebsite or bookstores. Under the new agreement the NOOK will now also be available via the Best Buy website and retail locations. To highlight the availability of the NOOK, Best Buy stores will feature a special in-store display where customers can get some hands-on time with a NOOK and buy one with guidance provided by a Best Buy Blue Shirt.

The NOOK will retail for $259.99 at Best Buy stores. Best Buy will also feature BN e-reader software on select PCs, netbooks, tablets and smartphones offered by the retailer.
